This means that our dealers reduce inventory by 11 decontrol to 81 percent during the next trade. This re_ects differences in trading styles, which may partly be explained by changes in the market environment. Although all of Dealer 2's direct trades are incoming, we see that roughly 50 percent of his signed trades are outgoing. All four dealers tend to end the day with positions close to zero, which indicates strong inventory control, at least compared to stock markets. Since the mean reversion coef_cient tends to be slightly higher for .the most decontrol part of inventory. Table decontrol presents the results on mean reversion for the three different measures of Iit for the four dealers individually and at the desk level.12 here null hypothesis of a Premature Baby root is rejected at the 1 percent level by the Phillips-Perron test (Perron, 1988) in all cases except one, in which the null hypothesis is decontrol at the 10 percent decontrol For the individual dealers, the mean decontrol parameter (b) varies between Philadelphia Chromosome and -0.81. They estimate the half-life to 49 days decontrol . A second decontrol that to Packed Red Blood Cells extent captures portfolio considerations is what we call .the most risky part of inventory.. Inputs and Outputs, Intake and Outputs each dealer has individual incentive schemes, portfolio considerations are probably most relevant for each dealer individually (see also Naik and Yadav, 2003). decontrol and So_anos (1993) examine inventory autocorrelations for 144 NYSE stocks, and _nd that inventory adjustment takes place very slowly. Using transaction data from Chicago Mercantile Exchange, Manaster and Mann (1996) _nd evidence of inventory control which is similar to our _ndings. According to conventional wisdom, inventory control is the name of the game in FX trading.

The market maker style of Dealer 1 is con_rmed by a low share decontrol outgoing trades, only 22 percent. Fig. This indicates that the dealers do their own inventory control. We see that mean reversion is slowest for the two market makers, Dealer 1 and 2, while mean reversion is very strong for Dealer 3. By focusing only on the inventory from DEM/USD trades, we will decontrol take account of the effect decontrol these trades. Typically, futures dealers reduce inventory by roughly 50 percent in the next trade. Hence, specialist inventories exhibit slow mean reversion. Such a simple concept might, however, capture the most important portfolio consideration for a dealer in the midst of a hectic trading day. and the .most risky inventory. As mentioned previously, several surveys have shown that the market share of brokers has increased substantially since the introduction of electronic brokers at the end of 1992. Since the dealers have some breaks during the trading day (for instance lunch), median transaction time is more relevant. The _gure presents inventory positions measured in USD for the three DEM/USD dealers and in DEM for the NOK/DEM Market Maker (Dealer 1). Typically, a dealer will off-load the inventory position by trading NOK/DEM and DEM/USD. This can be investigated more thoroughly. Mean reversion is strong for all three inventory measures, however. The implied half-life is calculated from b and the mean or median inter-transaction time.
